GALLAGHER, OF WATERTOWN, NEW YORK, ASSIGNOR TO .THE IBAGL EY AND SEWALL COMPANY, OF WATERTOVVN, NEW YORK, A CURPOIRATION OF NEW YORK 'WINDER ROLL FOR PAPER MAKING MACHINES Application filed September 29, 1927. Serial No. 222,703.

This invention relates to certain improvements in guide collars for the winder rolls on V which a web of paper is wound in paper mills.

These guide collars are used with the wind- 1 ing spindles on which the finished Web of paper is wound in paper mills for shipment. In winding these rolls there is a spindle on which the paper is wound and, during the winding operation, there is a tendency of the paper to wind unevenly, and to prevent this these guide collars are used to cause the paper to wind evenly on the roll.

It is the especial object of the present invention to provide a guide collar which can 16 be quickly locked to and removed from locking engagement with the roll spindle, which shall be of simple form, free of, any protruding parts which might endanger the operator, and which, if desired, can be manipulated 80 while the spindle is rotating. 7

A further object of the invention is to provide a collar construction and locking means therefor which can be locked and unlocked by a simple rotary movement, and which shall be of few parts but durable and sate.

With these and other objects not specifically referred to in view, the invention consists in certain novel parts, arrangements and combinations which will be described in con- 80 nection with the accompanying drawings and the novel features pointed out in the claims hereunto annexed.

In these draWings,- Figure 1 is a side elevation, partly broken away, showing the improved collar;

Figure 2 is a perspective view of one of th collars and its locking means;

Figure 3 is a section taken on the line 33 of Figure 2;

Figure 4 is a detail end view of the collar, and

Figure 5 is a detail of the locking means. Referring now to these drawings, the web WV is wound on a spindle l, which is supported in the winder so that it can be rotated in any suitable way, not shown. Mounted on this spindle, on eachside of the web roll, is v a collar for guiding the web as it is wound. As the construction of these collars is ormay be identical, a description of one will suffice for all. i l i In accordance with the invention, means are provided whereby the collars may be locked to and unlocked from the spindle rapidly and preferably while the spindle is revolving andin which there are no projecting parts which might be liable to injure an operator. VYhile the specific construction'ot the collar and the locking means may be somewhat varied, in the best constructions, this locking will be effected by the provision or" a member which may be actuated to effect this locking function by a rotary movement in one direction and released from looking en gagement by a rotary movement in the opposite direction.

In the particular construction illustrated, there is provided a collar 2. This collaris provided with a sleeve 3 to which is secured, by screws 4, a holding plate 5, which preferably is slightly recessed, as indicated at 6, to receive the end of the sleeve, thus being snugly held in position. This plate, is recessed at a plurality of points to receive bushings or blocks 7, three such bushings or blocks being shown. These bushings act to hold locking rolls 8 and preferably are, as shown at 9, split bushings, which receive the reducedv end 10 of the roll, thebushings being clamped by means of screws 11. Cooperating with these-rolls is an eccentric locking ring 12 having eccentric inner surfaces 13 which engage the rolls, this ring being located between the collar 2 and the face plate 5 and being held-in position by the latter, as shown in'Figure 3. The locking ring is ormay bel grooved, as indicated at 14:, to provide a sur face by which it may be readily grasped by the operator. V

It will be seen that by revolving the ring. in one direction, because of its eccentric inner surface, it will close in on the rolls and thus lock the collar to the spindle. \Vhile'turning in the opposite direction the rolls will be released and the whole collar may be easily slipped off thespindle. This can be done in a very rapid manner and While the spindle is rotating. It will be observed that there are no projecting parts by which an operator would be liableto catch his hand, and a very simple and at the same time a safe structure is provided.

If desired, means may be employed for preventing accidental displacement of the ring under ordinary conditions of use and a simple locking means for doing this has CAD been illustrated. As shown, there is supported in the face plate a spring seated ball 15' which Will drop into a slight recess in the ring when the ring is rotated and thus act to prevent accidental disengagement of the locking ring. The blocks or bushings. 7 are preferably made of fibre and these act as a slight brake on the rolls, tending to keep them in place when the locking ring is rotated to set the collar.

WVhile the invention has been shown and described in its preferred form, it will be understood that various changes can be made in the specific construction and arrangement of the parts without departing from the invention as claimed in the appended claims.

What I claim is:

1. In a winding mechanism, the combination of av winding spindle, a guide collar on the spindle, a sleeve on the collar provided with openings, a holding plate secured outside the sleeve, locking devices having a bearing in the holding plate and held in the sleeve openings so as to engage the spindle, and a rotary eccentric member engaging the locking devices and acting to move the locking devices into locking relation with the spindle,

2'. In a winding mechanism, the combination of a winding spindle, a guide collar on the spindle, a sleeve on the collar provided with openings, a holding plate secured outside the collar, bushings in the plate, rolls mounted in the bushings and held in the sleeve openings so as to engage the spindle, and a rotary eccentric engaging the rolls and acting'to force them into locking relation with the spindle.

3. In a: winding mechanism, the combination of a winding spindle, a guide collar on the spindle,'a sleeve on the collar provided with openings, a holding plate secured to the end of the sleeve and provided with recesses, bushings in the recesses, locking rolls having a bearing in' the bushings and held in the sleeve openings so as to engage the spindle,

and a rotary locking ring havingan. inner eccentric surface engaging the rolls and acting to force them into locking relation with the spindle.

4. In a winding mechanism, the combination of a winding spindle, a guide collar on the spindle, a sleeve on the collar having openings, a recessed holding plate secured to the end of the sleeve, split bushings, locking rolls mounted in the bushings and held in the sleeve openings.- so as to engage the spindle, a rotary locking ring having an inner my hand. 7
